Wheel Hub Bearing Installation & Compatibility Guidelines

Recommended Installation Procedure:

1. Ensure vehicle is securely lifted with hybrid system properly disabled

2. Remove wheel, brake caliper, and rotor assembly

3. Disconnect ABS sensor connection if required

4. Remove existing hub bearing using appropriate extraction tools

5. Clean all mounting surfaces on steering knuckle

6. Install new hub bearing assembly, torquing to manufacturer specifications

7. Reconnect all electrical connections and reassemble brake components

8. Perform system check and test drive

Hybrid-Specific Considerations:

• Special care recommended when working near high-voltage components

• Ensure ABS sensor alignment for proper regenerative braking functionality

• Verify wheel speed sensor operation post-installation
